The per-webhook archiveWriter registry in the database delivery target
was never evicted, so a deleted webhook's writer -- and any archive
file handle open within its debounce window -- lingered for the process
lifetime. Separately, expiry pruning ran only when an archive was
(re)opened, and reopens only happen on writes, so an archive belonging
to a webhook that stopped receiving events kept its expired rows
forever.
Eviction: a new one-method delivery.WebhookEvictor interface (kept
separate from Notifier: archiving lifecycle is not notification) is
implemented by the Engine and injected into the handlers. Deleting a
webhook, or deleting its last database target, drops the writer from
the registry and closes its handle under the writer's own mutex, so
eviction can never race an in-flight write. An evicted writer refuses
further writes rather than reopening a file nothing holds. The archive
file is deliberately left on disk: it is long-term storage an operator
may want to keep or move away, and destroying it as a side effect of
deleting a webhook would be unrecoverable.
Idle sweep: a new ArchiveSweeper, modelled on the event RetentionReaper
(fx lifecycle hooks, cancellable context, WaitGroup, ticker loop),
prunes archives whose database target declares a positive expiry. It
reuses the existing RETENTION_SWEEP_INTERVAL rather than adding a
config key. It never creates an archive -- a missing file is skipped,
and the reopen uses SQLite mode=rw so the file cannot be conjured even
if it disappears mid-sweep -- routes the prune through the per-webhook
writer so its mutex orders the sweep against concurrent writes, and
leaves the archive closed so the move-the-file-away workflow keeps
working. A failure for one webhook is logged and the sweep continues.
Archives with no expiry or the expiry "never" are untouched.
The sweep loop's context is rooted at context.Background(), not at the
fx OnStart hook context. The hook context carries fx's 15 second start
timeout, so a loop derived from it is cancelled three quarters of an
hour before the first tick under the default one-hour interval, giving
a sweeper that never sweeps. OnStop still cancels the loop and waits on
the WaitGroup, so shutdown is unchanged.
The sweep also never leaves a registry entry behind. Reaching the
writer through the ordinary create-and-cache accessor would let a sweep
that raced a webhook deletion re-insert a writer for a webhook that no
longer exists, which nothing would ever evict again -- the very leak
this change closes. An entry the sweep has to create is marked
sweep-owned and released when the prune finishes, unless a delivery
claimed it meanwhile, in which case it belongs to the registry and an
eviction can still reach it. A writer evicted underneath a sweep is an
ordinary interleaving and is logged at debug, not error.
Bumps golangci-lint from v2.11.3 to v2.12.2 and adopts the canonical lint config.
## Version pins
- `Dockerfile`: `golangci/golangci-lint:v2.12.2` Debian image, pinned by digest, dated `2026-08-07`
- `script/bootstrap`: `GOLANGCI_LINT_VERSION=2.12.2` with updated sha256 pins for the `linux-amd64` and `linux-arm64` release archives
## Config
`.golangci.yml` replaced with the canonical config. The previous file kept `lll`/`funlen`/`cyclop`/`dupl` settings under the top-level `linters-settings` key, which the v2 schema ignores; the canonical config nests them under `linters.settings`, so those thresholds now actually apply. The unsupported `issues.exclude-use-default` key was dropped.
## Lint fixes (32 findings)
- `lll` (7): wrapped or shortened over-length lines (struct tag comments moved above fields, test logger construction split, `session.NewForTest` signature wrapped, shortened a `#nosec` comment)
- `goconst` (17): replaced repeated `"POST"`/`"PUT"` literals with `http.MethodPost`/`http.MethodPut`, added shared test constants for `webhooker-test`/`test`/`application/json`, and added `tmplKeyError`/`tmplKeyWebhook` constants for template data keys in `internal/handlers`
- `dupl` (8): merged `buildHTTPTargetConfig` and `buildSlackTargetConfig` into a parameterized `buildURLTargetConfig`; removed the duplicate `iWebhookDB` test helper in favor of `testWebhookDB`; extracted shared helpers in middleware and session tests
No `//nolint` directives were added and behavior is unchanged. `make check` (fmt-check, tests, lint) passes.
Note: golangci-lint v2.12 deprecates the `gomodguard` linter in favor of `gomodguard_v2`; the canonical config change for that is left for a future coordinated update.

## Summary
This PR brings the webhooker repo into full REPO_POLICIES compliance, addressing both [issue #1](#1) and [issue #2](#2).
## Changes
### New files
- **`cmd/webhooker/main.go`** — The missing application entry point. Uses Uber fx to wire together all internal packages (config, database, logger, server, handlers, middleware, healthcheck, globals, session). Minimal glue code.
- **`REPO_POLICIES.md`** — Fetched from authoritative source (`sneak/prompts`)
- **`.editorconfig`** — Fetched from authoritative source
- **`.dockerignore`** — Sensible Go project exclusions
- **`.gitea/workflows/check.yml`** — CI workflow that runs `docker build .` on push to any branch (Gitea Actions format, actions/checkout pinned by sha256)
- **`configs/config.yaml.example`** — Moved from root `config.yaml`
### Modified files
- **`Makefile`** — Complete rewrite with all REPO_POLICIES required targets: `test`, `lint`, `fmt`, `fmt-check`, `check`, `build`, `hooks`, `docker`, `clean`, plus `dev`, `run`, `deps`
- **`Dockerfile`** — Complete rewrite:
- Builder: `golang:1.24` (Debian-based, pinned by `sha256:d2d2bc1c84f7...`). Debian needed because `gorm.io/driver/sqlite` pulls `mattn/go-sqlite3` (CGO) which fails on Alpine musl.
- golangci-lint v1.64.8 installed from GitHub release archive with sha256 verification (v1.x because `.golangci.yml` uses v1 config format)
- Runs `make check` (fmt-check + lint + test + build) as build step
- Final stage: `alpine:3.21` (pinned by `sha256:c3f8e73fdb79...`) with non-root user, healthcheck, port 8080
- **`README.md`** — Rewritten with all required REPO_POLICIES sections: description line with name/purpose/category/license/author, Getting Started, Rationale, Design, TODO (integrated from TODO.md), License, Author
- **`.gitignore`** — Fixed `webhooker` pattern to `/webhooker` (was blocking `cmd/webhooker/`), added `config.yaml` to prevent committing runtime config with secrets
- **`static/static.go`** — Removed `vendor` from embed directive (directory was empty/missing)
- **`internal/database/database_test.go`** — Fixed to use in-memory config via `afero.MemMapFs` instead of depending on `config.yaml` on disk. Test is now properly isolated.
- **`go.mod`/`go.sum`** — `go mod tidy`
### Removed files
- **`TODO.md`** — Content integrated into README.md TODO section
- **`config.yaml`** — Moved to `configs/config.yaml.example`
## Verification
- `docker build .` passes (lint ✅, test ✅, build ✅)
- All existing tests pass with no modifications to assertions or test logic
- `.golangci.yml` untouched
closes #1
closes #2
